IMPROVEMENT IN RAILWAYS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, EDWARDG. MARKLEY, of Sunbury, in the county of Northumberland 'and State of Pennsylvania, have invented a new and useful Improvement in Railroad Silis; and do hereby declare that the, following description, taken in connection with the accompanying plate of drawings hereinafter referred to, forms a full and exact description of the same, wherein I have set forth the nature and principles of my said improvement, by which my said invention maybe .distingished from others of a similar class, together with such parts as 'I claim and desire to secure by Letters Patent.

My invention relates t6 that class of railroad superstructure,t the office of which is to support, connect, and hold iu position the rails, and the nature thereof consists in certain modifications in the details and iinprovements in the construction of thc same, by means of which the rails are so coupled or jointed as to maintain a perfect level; the use of wooden sills or crossties is done away with the necessity of preparing the bed-road oliviated; economy' of construction facilitated; durability insured.

Ihe design or object of my invention is to supersede the present mode of constructing railroad superstructure, to dispense with wooden sills, chairs, spikes, 85e., and to substitute an arrangement of devices which will combine economy and safety of travel.

In the accompanying plate of drawings which illustrates m'y invention, and forms apart of the speciiication thereof, in which correspoinling` parts'are illustrated` by similar letters- Figure l is a side elevation Figure 2 represents a plan;

Figure 3, a transverse vert-ical section; andI Figure 4 is a plan view.

The construction, operation, and relative arrangement of the component parts of my invention are as follows, to wit:

A represents an upright block, constructed of castiron, and having the form of a truncated cone.

Upon the top of the said cone, and constructed of one and the same piece therewith, is Hauch B, which fornis the chair in andupon which the rails rest.

Upon the top of the said Hauch is cast the elongated tapering slot D, provided with shoulders d to fit the rail and the wedge-shaped key E.

` Upon the lower side of the said key is cast the shoulder e, and upon the upper side thereof the shoulder e, which fit respectively iu the receptacles in the Hauch and rails, as shown.

\ The conical block hijs/hollow, and may bc provided with shoulders a, upon which can be placed apad of wood or rubber to ease off the downwardv pressure of the rails.

Upon one side of the said block is cast or otherwise secured, the eye-bolt F, in which is fastened the tie H, which connects the said block with its fellow on the opposite side of the track.

Tosecure the rails I upon and within the Hauch or seatB the said rails are so placed that the ends there of rest upon the center of the seat, and one side of the broad bottoms thereof is introduced within the receptacle cast for its reception, as aforesaid. The key E is then introduced and fitted, as hercinbefore described, in such a manner as to hold the rail iirmly in position.

After heilig so introduced, the key is held in position by means of a pin, e2, passing through -aperfoi-ation cut therein. By this means the rails are firmly and evenly united within the embrace of thc chair and key.

The connecting-tic H extends across the road from one block tothe other, and is located at such a distance from the top thereof as to be sunk below the grade of the road and covered over with earth. this arrangement the sills opposite to each other on either side of the road will be bound together in such a manner as to resist any lateral pressure produced by `heavy trains passing over the rails, and thc necessity of preparing a bed for cross-ties obviated.

The bottom of the block A may be provided with a Hauch sufficiently broad to maintaiuthe uprightness thereof when inserted in the ground. The bottom or base of the receptacle for the reception 0i' the block may be filled in with a few inches of ,pounded stone, with a top dressing of a little earth well rammed down and made peifectly level. But when the earth is of solid texture this operation may be omitted. The block may be constructed of such a size as to extend downward below the reach of the effects of frost, thereby obviating ditliculties occasioned thereby.

Having thus described my invention,

I will indicate what I claim, and desire to secure by Letters Patent, in thc following clause:

The hollow conical block A, provided with the elongated tapering slot D for thereception of the key E, and constructed with shoulder a for the reception of an elastic pad, when combined with thc rails I, as and forthe purpose described.

,EDWARD G. MARKLEY.
